Safety
Seat belts
Inertia reel
The seat belts are equipped with an inertia
reel which allows the strap length to adjust
automatically to the shape of the user. The seat
belt returns to its storage automatically when it
is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Progressive force limiting system
This system reduces the pressure of the seat
belt on the chest of the occupant, taking their
stature into account, thus improving their
protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a PEUGEOT dealer or a qualified
workshop.
Front seat belts
The front seat belts are fitted with a pyrotechnic
pretensioning system and a progressive force
limiting system.
Rear seat belts

Each of the rear seats has a three-point seat belt
with inertia reel.
The outer seats are fitted with a pyrotechnic
pretensioning and force limiting system.
Fastening
► Pull the strap, then insert the tongue into the
buckle.
►

Check that the seat belt is fastened correctly
by pulling on the strap.
Unfastening
► Press the red button on the buckle.
► Guide the seat belt as it is reeled in.

the rear passengers has not fastened their seat
belt, the corresponding warning lamp ( 3, 4 or 5)
comes on in red for 1 minute.
Seat belt unfastened alert
After the ignition is switched on, if the
driver or a passenger unfastens their seat belt,
the corresponding warning lamp ( 1, 2, 3, 4 or
5) comes on in red. At a speed greater than
12 mph (20
km/h), the warning lamp flashes,
accompanied by an audible signal for around 2
minutes. After this time has elapsed, the warning
lamp remains on until the seat belt has been
fastened again.
With the ignition on, if the driver or a
passenger fastens their seat belt, the
corresponding warning lamp ( 1, 2, 3, 4 or 5)
comes on in green on the display.
With the ignition on, if one of the front or
rear passenger seats is detected as being
unoccupied, the corresponding warning lamp ( 2,
3, 4 or 5) comes on in grey on the display.
When there are no longer any not fastened/
unfastened alerts, the green or grey warning
lamps remain on for around 30 seconds, then
go off.
Advice
The driver must ensure that passengers use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not invert the seat belt buckles, as they
will not fulfil their role properly.
To ensure the proper functioning of the belt
buckles, make sure that there are no foreign
bodies present (e.g.
a coin) before fastening.
Before and after use, ensure that the seat belt
is reeled in correctly.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Installation
The lower part of the strap must be
positioned as low as possible over the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
At the front, adjusting the position of the
seat belt may require the seat height to be
adjusted.
In order to be effective, a seat belt must:
– be tightened as close to the body as
possible.
–

be pulled in front of you with a smooth
movement, checking that it is not twisted.
–


must only be used to secure one person.
–


not show signs of tearing or fraying.
–


not be changed or modified, in order to
avoid affecting its performance.
Recommendations for children
Use a suitable child seat if the passenger
is less than 12 years old or shorter than 1.5
metres.
Never use the same seat belt to secure more
than one child.
Never carry a child on your lap.
For more information on Child seats, refer to
the corresponding section.
Maintenance
In accordance with current safety
regulations, for all work on your vehicle's
seat belts, contact a qualified workshop with
the skills and equipment needed, which a
PEUGEOT dealer is able to provide.
Have the seat belts checked regularly by a
PEUGEOT dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy water or
a textile cleaning product, sold by PEUGEOT
dealers. CarM an uals 2 .c o m

Safety
5Lateral airbags

This system protects the driver and front
passenger in the event of a serious side impact,
limiting the risk of injury to the chest, between
the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest
frame, on the door side.
Deployment
The lateral airbags are deployed on one side in
the event of a serious side impact applied to all
or part of the side impact zone B.
The lateral airbag inflates between the chest of
the vehicle's occupant and the corresponding
door panel.
Curtain airbags
This system helps provide greater protection for
the driver and passengers (with the exception
of the rear centre passenger) in the event of a
serious side impact, in order to limit the risk of
injury to the side of the head.
Each curtain airbag is built into the pillars and
the upper passenger compartment area.
Deployment
It deploys simultaneously with the corresponding
lateral airbag in the event of a serious side
impact applied to all or part of the side impact
zone B.
The curtain airbag inflates between the front
and rear occupants of the vehicle and the
corresponding windows.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel. Contact a PEUGEOT
dealer or a qualified workshop to have the
system checked.
The airbags may not be deployed in the event of
a serious impact.
In the event of a minor impact or bump at
the side of the vehicle or if the vehicle
rolls over, the airbags may not be deployed.
In the event of a rear or front collision, none of
the lateral airbags are deployed.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting position.
Fasten your seat belt and position it correctly.
Do not place anything between the occupants
and the airbags (e.g.
child, animal, object), do
not fix or attach anything near or in the path of
the airbags, as this could cause injuries when
they are deployed.
Never modify the original definition of the
vehicle, particularly in the area directly around
the airbags.
Even if all of the precautions mentioned are
observed, a risk of injury or of minor burns to
the head, chest or arms cannot be ruled out
when an airbag is deployed. The bag inflates
almost instantly (within a few milliseconds)
then deflates within the same time,
discharging the hot gas via openings provided
for this purpose.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work must be carried out only by a
PEUGEOT dealer or a qualified workshop
Front airbags
Do not drive holding the steering wheel
by its spokes or resting your hands on the
centre part of the wheel. CarM an uals 2 .c o m

82
Safety
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fix or attach anything to the steering
wheel or dashboard, as this could cause
injuries when the airbags are deployed.
Lateral airbags
Use only approved seat covers
compatible with the deployment of these
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
PEUGEOT dealer.
Do not fix or attach anything to the seat
backrests (e.g.
clothing) as this could cause
injuries to the chest or arm when the airbag is
deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
All work must be carried out only by a
PEUGEOT dealer or a qualified workshop
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof.
Active bonnet

The active bonnet has been designed to
optimise the safety of pedestrians in the event of
collision with the front of the vehicle.
The pyrotechnic system is triggered at the
hinges of the bonnet to lift it, when the sensors
located at the front of the vehicle detect a
collision.
Deployment of the active bonnet is
accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system. The airbag
warning lamp comes on.
After triggering, do not try to open or close
the bonnet. Call a towing company or go to
the nearest PEUGEOT dealer or qualified
workshop, driving at a speed below 19 mph
(30
km/h).
Make sure that you adjust the height of the
driver's seat - risk of hindrance to visibility!
This equipment will only trigger once. If a second impact occurs (during the same
or a subsequent accident), the active bonnet
will not trigger.
After an accident or if the vehicle has been
stolen, have the system checked.
Do not tamper with the pyrotechnic systems
under the bonnet, close to the struts - risk of
explosion!
All work must be carried out only by a
PEUGEOT dealer or a qualified workshop
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal. You must contact a PEUGEOT
dealer or a qualified workshop to have the
system checked.

Driving
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine PEUGEOT towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact a PEUGEOT dealer.
Starting/switching off the
engine
The electronic key must be present in the passenger compartment.
The electronic key is also detected in the
boot.
If the electronic key is not detected, a
message is displayed.
Move the electronic key so that the engine
can be started or switched off. CarM an uals 2 .c o m

Special cases
Immobilising the vehicle with the
engine running
To immobilise the vehicle with the engine
running, briefly pull the control.
Parking the vehicle with the brake
released
In very cold conditions (ice), applying the
parking brake is not recommended.
To immobilise the vehicle, place the chock
against one of the wheels.
Mode P is automatically selected when
the ignition is switched off. The wheels
are blocked.
For more information on Free-wheeling, refer
to the corresponding section.
If you open the driver's door while mode
N is engaged, an audible signal will
sound and mode P will be engaged. The
audible signal stops when the driver's door is
closed.
Deactivating automatic
operation
In some situations, for example when it is
extremely cold or when towing (e.g. caravan, breakdown), it may be necessary to deactivate
automatic operation of the system.
►

Start the engine.
►

Use the control to apply the parking brake, if
it is released.
►

T
ake your foot fully off the brake pedal.
►
Keep the control pushed in the release
direction for 10 to a maximum of
15 seconds.
►
Release the control.
►

Depress and hold the brake pedal.
►

Pull the control in the application direction for
2
seconds.
This indicator lamp on the instrument
panel comes on to confirm deactivation of
the automatic functions.
►

brake to be applied and released.
►


Follow this procedure again to reactivate
automatic operation (confirmed by the indicator
lamp on the instrument panel going out).
Emergency braking
If depressing the brake pedal fails to provide
effective braking or in exceptional circumstances
(e.g.
driver unwell, assisted driving), the vehicle
can be braked by sustained pulling on the
electric parking brake control. Braking continues
for as long as the control is kept pulled, and
ceases when the control is released.
The ABS and DSC systems stabilise the vehicle
during emergency braking. If emergency braking malfunctions, the message
"Parking brake fault" will be displayed on the
instrument panel.
If the ABS and DSC systems
malfunction, indicated by lighting
one or both warning lamps on the instrument
panel, the vehicle’s stability is no longer ensured.
►

In this case, ensure the vehicle's stability by
successive and repeated "pull-release" actions
on the electric parking brake control until the
vehicle comes to a complete stop.
